I have only had this laptop for the last couple day. But I did my best to put the battery through it's paces. Between getting all the updates for the software and transferring all my photos/videos/documents/etc, the battery gave me a solid 5 hours. From all the reviews I read, if using the basic stuff (listening to music while writing a paper or watching youtube) then the battery can last anywhere from 7-10 hours. It all depends on what you are doing, how you have your preferences set up and so forth. But for a PC, I feel anything over 5 hours is worth the price unless you are going for a MacBook Pro.
